A spring is compressed by tying its ends together tightly. It is then placed in acid and dissolves. What happens to its stored potential energy?

1 Answer

The potential energy of the system increases when the spring is compressed by tying its ends together tightly. When the compressed spring placed in acid, the entropy of the system increases, as a result, the molecules will come together closely and they collide. Thus, the temperature of the system will increase results the spring will dissolve in the acid.
